I tend to use a cream or spray protector for the initial part of my styling post-wash. So while my hair is damp, I’ll apply it in sections and dry it a bit at a time. Then when my hair is completely dry, I’ll apply a styling serum/oil hybrid like the L’Oréal Professionnel Serie Expert Absolut Repair 10 in 1 Leave In Oil, as it gives further protection, and my hair feels silky smooth after using it. I’ve found this extra step especially important now my hair is bleached.
Good news, though: If you restyle between washes, you don’t need to reapply. “If you use a professional heat-protection spray such as Wella Professionals EIMI Thermal Heat Protection Spray and your styling tool does not exceed the temperature of 185ºC, your hair will be protected from heat damage until the next wash,” says Cobella. “However, it is important to note that excessive heat past 185ºC can cause irreversible damage to the internal structure of the hair, which heat protection cannot guard against.”
Through my adventures in heat-styling my hair, I have tried hundreds of heat protectors, and these are by far the best on the market.
